Abstract

Excessive heat production resulting from the overuse of power supply poses a significant challenge in embedded systems, with heightened concerns in medical devices. In the medical field, this issue becomes even more critical, as overheating can pose dangers to patients and, in severe cases, lead to serious consequences. Therefore, this master's thesis is dedicated to design and implement temperature and voltage control software for a medical device in order not to provide too much heat because of using highly inappropriate voltage. The software's primary objective is to efficiently manage and regulate the operating voltage, current, and power supply across various components, aiming to enhance the gas sensor's performance and achieve optimal efficiency. The research encompasses both the design aspects of the software and its practical implementation, involving rigorous testing to assess the system's reliability. Additionally, additional testings between the software with the PID control and the one without PID control will be conducted to identify and address potential issues in this new control system. The goal of this research is to mitigate temperature-related risks associated with prolonged operation and overpowering of the sensor. The proposed control loops aim to ensure that the gas sensor's surface temperature remains within the optimal range as required by the International Electrotechnical Commission (IEC) standards, thereby enhancing the overall safety and performance of the same medical device.
